When they spun it hard enough to get the pressure we needed it was making too much heat because it was out of its efficiency range ON MY APPLICATION. Its perfectly happy on a mostly stock LS3 though which is what it was designed for. Its a damn fine piece of kit so I'm not knocking it whatsoever! We could have just moved up a model to a higher volume unit but its designed differently in regards to the heat exchanger etc and Hennessy and I were both eager to try out twin turbos once we started looking at options.
Another option for the use of a twin screw on this type of build could be the larger size Kenne Bell. Just a guess.
Still, twin turbos are the shizznit. Amazing car you have there.
